Model and reality show host Heidi Klum seems stress-free about losing the extra baby weight with baby number four. Six weeks after giving birth to Lou Sulola, Klum had already lost 25 pounds, just in time for her to host the Victoria's Secret Fashion Show. Klum attributes her weight loss to light cardio workouts and swears she didn't diet. "I still have 20 lbs. to go, but there's no master plan," she told People.
